SECTIONAL TUBULAR HANDLE FOR TOOLS.

Specification of Letters Patent.

Eatented March 9, 1909.

To all iii/0cm it may concern:

Be it known that we, rimmer H. COOLEY outside ot the threaded portion 0to receiye the-right hand end of the tube A. lVrthin and llnnnnu'r E.Minus, citizens of the i the tube A there is provided a bolt B on UnitedStates, and residents, respectively, of lh-ockport, Monroe county, andPoughkeepsic, Dutchess county, ljtate of New York, have invented a. newand improved Sectional Tubular Handle for Tools, of which the followingis a specification.

This invention relates to handles for picks, hammers and other liketools, the object being to provide a tubular metallic handle for suchtools and means whereby such a handle may be readily inserted andsecured within the eye ofthe tool.

Another object is to provide means whereby the handle may be formed insections with the parts thereof effectually and economically securedtogether and with the parts of the handle making a threaded connoct'ionwith a member operating to secure the handle in the tool.

The accompanying drawings illustrating our invention are as follows:-

Figure l is a side View of a pick with a handle inserted and secured inplace therein,

such handle and pick shown partially in sec tion. Fig. an end View, asseen from the left, olithe parts shown in Fig. 1. Fig. 3 is a side \"lOWof the left hand portion of the handle seen in Fig. 1 shown partially insection, the plane oi the section, however, being at right angles tothe, plane of the section shown in Fig. 1. Fig. a shows in a view quitesimilar to Fig. 1 a modification of our handle adapted to use withshovels, while Figs. 5 and'tl show different styles of the detachable orextension portion of such a handle, for use with shovels.

Similar letters refer to similar parts throughout. the several views.

Referring to Figs. 1, 2 and 3,-1. is the pick, shown partially invertical section and is the outer member of the handle coniprisingr aconically formed tubular section, the Oilttlfdlltl of which is formedinto a head or roll a. which may contain a rcinforcing; wire v andaround which such head or roll may he formed; The tube is as to titquite closely, at. its outer end, the eye of the tool. The right handend oi? the tube is internally threaded to receive the enternallythreaded slcerec on the coupling cou )lin C has a central. extensionrooved a D 2::

l l l l 2 l i l l l l 1 larged at its left hand end and passing throughthe wedging washer of disk w, i iretcrably of wood or fiber, althoughmetal may be used. This bolt B is tapered at a point just within theinner edge'ot' the eye of the tool and is threaded through a sectionalnut 11, such nut n adapted upon the screwing up of the bolt B to expandin a direction transversely t0 the plane of Fig. l, as indicated in Fig.3, the purpose being to force outwardly and expand the walls of the tubeA just within the inner edge of the of the tool, and for this purposethe eye of the tool may preferably be slightly tapered, to an extent,however, not perhaps appreciable to the nalied eye but sufficiently toproduce the necessary wedging action to prevent the tool P from slippingupwardly on the handle. Thebolt B extends to the right within the tube Aand its extreme right hand'end is threaded to receive a nut on therighthand or inner face of the central web of the coupling C.

The nethod of assembling and the action oi the parts thus far describedis as followsz lhc tube A is inserted through the eye of the tool 1 andthen the bolt B with the sectional nut 11. thereon is torced intoposition, substantially such as shown in Fig. l,

but with the bolt 3 projecting,- outwardly to the. lett beyond the outerend of the handle.

The washer n: then inserted over the end oi the bolt and the nut I)screwed down thereon. lly properly adjusting the parts,

the washer u will be forced to its final position by the bolt. ll at.about. the time that the nut. a has been sulliciently expanded to forcethe wall ot the tube A. outwardly to secure the desired wedpginn actionto prevent the sliding: of the tool 1* upwardly on the handle. Al thesame time the washer 2 and out n will be drawn sonuiwhat together,causing the washer to to firmly wedge within the outer end of the tul eI. and *l'orce the same outwardly lirmly against the wall of the eye orsocket in the tool l. The coupling meu'rber I may then be secured overthe right hand end of the bolt l4 and screwed into place within the tubeIt, and 'When firmly setewedto position the nut b may be inserted andalso screwed tirnily up gainst the web of the coupling C.
